Older Dublin homes are full of character and charm — but when it comes to heating efficiency, they can present real challenges. Draughts, outdated boilers, and poor insulation often lead to higher energy bills and inconsistent warmth during the colder months.

At Borough Gas Heating and Plumbing, we specialise in helping homeowners upgrade and optimise their gas heating systems. Here’s how you can improve heating efficiency in older Dublin properties while keeping your home comfortable and cost-effective.

1. Upgrade to a Modern High-Efficiency Gas Boiler

If your boiler is over 12–15 years old, it may be operating at significantly lower efficiency than modern models. Older non-condensing boilers can waste a substantial amount of energy.

Upgrading to a modern A-rated condensing gas boiler can dramatically reduce gas consumption and improve heating performance. Newer systems are designed to extract more heat from fuel, meaning lower energy bills and reduced carbon emissions.

Always ensure your boiler installation is carried out by a technician registered with the Registered Gas Installers of Ireland (RGI) to guarantee safety and compliance.

2. Schedule Annual Boiler Servicing

Even if your boiler is relatively modern, regular servicing is essential. Over time, components can become dirty or worn, reducing efficiency.
An annual gas boiler service ensures:

• Safe combustion
• Clean internal components
• Proper pressure levels
• Early detection of faults

Routine servicing keeps your heating system operating at peak performance, particularly during Dublin’s colder months.

3. Install Smart Heating Controls

Older Dublin homes often rely on basic manual thermostats. Installing smart heating controls or programmable thermostats allows you to manage heating schedules more effectively.

Smart systems let you:

• Heat only occupied rooms
• Adjust temperatures remotely
• Reduce unnecessary energy usage
• Improved control equals improved efficiency — and lower bills.

4. Power Flush Your Heating System

In older properties, sludge and debris can build up inside radiators and pipework over time. This restricts water flow and reduces heat output.
A professional power flush removes blockages, improves circulation, and helps your boiler operate more efficiently. If your radiators have cold spots or take a long time to heat up, this could be a sign your system needs flushing.

5. Improve Insulation and Reduce Heat Loss

While upgrading your heating system is important, reducing heat loss is equally essential. Older homes may benefit from:

• Attic insulation upgrades
• Draught proofing around doors and windows
• Lagging hot water pipes
• Upgrading to double glazing

Improving insulation allows your heating system to work less while maintaining consistent warmth.

6. Balance Your Radiators

Radiator balancing ensures even heat distribution throughout your home. In many older Dublin houses, some rooms overheat while others remain cold. Proper balancing improves comfort and reduces wasted energy.
